Write multiple if statements:

if caryear is before 1967, print "probably has few safety features." (without quotes).

if after 1970, print "probably has head rests.".

if after 1990, print "probably has electronic stability control."

if after 2002, print "probably has airbags.".

end each phrase with period and newline. ex: caryear = 1995 prints:

The angular surfaces of crushed stone make it perfect for forming flat surfaces when compacted or rolled. It makes a stable, interlocking base for concrete foundations, roads and floors.

Explanation:

A Carnot heat engine receives heat from a reservoir at 900$^\circ{}$C at a rate of 800 kJ/min and rejects the waste heat to the ambient air at 27$^\circ{}$C. The entire work output of the heat engine is used to drive a refrigerator that removes heat from the refrigerated space at -5$^\circ{}$C and transfers it to the same ambient air at 27$^\circ{}$C. Determine (a) the maximum rate of heat removal from the refrigerated space and (b) the total rate of heat rejection to the ambient air. Answers: (a) 4982 kJ/min, (b) 5782 kJ/min
